+Bluetooth connectivity, AI conversation capabilities, facial expression rendering, and dance choreography.
+
+## Features
+
+- 🤖 **Bluetooth Device Management** - Connect and control StackChan robots via BLE
+- 💬 **AI Conversation** - Natural language interaction powered by XiaoZhi AI
+- 🎭 **Facial Expression Rendering** - Real-time 3D face animation using Three.js
+- 🎵 **Music & Dance** - Create and play dance choreographies with music
+- 📷 **Camera Integration** - AR features and face detection
+- 🔐 **Secure Communication** - RSA encryption for data transmission
+
+## System Requirements
+
+- **Flutter SDK**: 3.0+
+- **Dart SDK**: 3.0+
+- **iOS**: 14.0+ (for iOS deployment)
+- **Android**: API 21+ (for Android deployment)
+- **macOS**: 11.0+ (for macOS deployment)
+## Installation
+
+### 1. Install Flutter
+
+Follow the official Flutter installation guide for your operating system:
+
+#### macOS
 
-## 1. Clone the repository
 ```bash
-git clone https://github.com/m5stack/StackChan
-cd StackChan/app
+# Download Flutter SDK
+git clone https://github.com/flutter/flutter.git -b stable
+export PATH="$PATH:`pwd`/flutter/bin"
+
+# Verify installation
+flutter doctor
 ```
 
-## 2. Open the project in Xcode
-Open the project in Xcode:
+#### Windows
 
-Double‑click the `.xcodeproj` file, or open Xcode → File → Open, then select the project.
+```bash
+# Download Flutter SDK from https://flutter.dev/docs/get-started/install/windows
+# Extract and add to PATH
 
-1. Select your target device or simulator.
-
-### Connect an iPhone (Optional but Recommended)
-- Connect your iPhone to the Mac using a USB cable.
-- Unlock the iPhone and tap **Trust This Computer** if prompted.
-- In Xcode, select your iPhone as the run destination at the top.
-
-### Enable Developer Mode on iPhone (iOS 16+)
-> **Important:** Developer Mode will only appear after the iPhone has been connected to Xcode at least once.  
-If you do not see this option, make sure your iPhone is connected to the Mac, unlocked, trusted, and recognized by Xcode.
-- On the iPhone, go to **Settings → Privacy & Security → Developer Mode**.
-- Turn on Developer Mode and restart the iPhone.
-- After restart, confirm enabling Developer Mode.
-
-## 3. Configure Signing & Capabilities
-This step allows Xcode to install the app on your iPhone.
-
-1. In Xcode, select the project in the left sidebar.
-2. Select the app target.
-3. Open the **Signing & Capabilities** tab.
-4. Sign in with your Apple ID (Xcode → Settings → Accounts → Add Apple ID).
-5. Set **Team** to your Apple ID.
-6. Change **Bundle Identifier** to a unique value, for example:
-`com.yourname.stackchan`
-7. Ensure no red error messages remain.
-
-> **Note:** A free Apple ID is sufficient for testing on your own iPhone.
-
-## 4. Modify network configuration
-Before running the app, you need to set the correct server IP:
-
-1. Open the file `Network/Urls.swift`.
-2. Find the line defining the base URL, for example:
-```swift
-// Base URL configured according to the server's IP
-static let url = "192.168.51.24:12800/"
+# Verify installation
+flutter doctor
 ```
-3. Replace the IP address (`192.168.51.24`) with the IP of the computer where the server is running.
-4. Save the file.
 
-## 5. Run the project
-Press `Cmd + R` to build and run the app.
+#### Linux
 
-> **Note:** The first build may take several minutes as Xcode prepares the environment.
+```bash
+# Download Flutter SDK
+git clone https://github.com/flutter/flutter.git -b stable
+export PATH="$PATH:`pwd`/flutter/bin"
 
-If running on an iPhone for the first time, you may need to trust yourself as a developer:
-- On your iPhone, go to **Settings → General → VPN & Device Management → Trust Developer** and trust the developer profile that appears.
+# Install dependencies
+sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev liblzma-dev
 
-The app will now connect to the server at the IP you configured.
+# Verify installation
+flutter doctor
+```
+
+### 2. Set Up Project
+
+```bash
+# Clone the repository
+git clone <repository-url>
+cd StackChan
+
+# Install dependencies
+flutter pub get
+```
+
+### 3. Configure Backend Server
+
+The application requires a backend server for full functionality. Configure the server endpoints before building:
+
+#### Option A: Using Environment Configuration (Recommended)
+
+Create a `.env` file in the project root or modify the configuration directly in code.
+
+#### Option B: Direct Code Configuration
+
+Modify `lib/network/urls.dart` to set your backend server URL:
+
+```dart
+// lib/network/urls.dart
+class Urls {
+  // Update this to your backend server address
+  static const String url = "your-backend-server:port/";
+
+// ... rest of the configuration
+}
+```
+
+#### Option C: Configure Value Constants
+
+Update `lib/util/value_constant.dart` for encryption keys and other constants:
+
+```dart
+// lib/util/value_constant.dart
+class ValueConstant {
+  // Server RSA Public Key for encryption
+  static const String serverPublicKey = """
+-----BEGIN PUBLIC KEY-----
+YOUR_SERVER_PUBLIC_KEY_HERE
+-----END PUBLIC KEY-----
+""";
+
+  // Client RSA Private Key for decryption
+  static const String clientPrivateKey = """
+-----BEGIN RSA PRIVATE KEY-----
+YOUR_CLIENT_PRIVATE_KEY_HERE
+-----END RSA PRIVATE KEY-----
+""";
+}
+```
+
+**Important**: For production deployments, use environment variables or secure key management instead of hardcoding
+keys.
+
+## Building the Application
+
+### iOS
+
+```bash
+# Install CocoaPods dependencies
+cd ios
+pod install
+cd ..
+
+# Run on iOS simulator
+flutter run -d ios
+
+# Build for release (iOS device)
+flutter build ios --release
+```
+
+### Android
+
+```bash
+# Run on Android emulator or connected device
+flutter run -d android
+
+# Build APK for release
+flutter build apk --release
+
+# Build App Bundle for Google Play
+flutter build appbundle --release
+```
+
+### Android Release Signing (JKS)
+
+For release builds (`apk --release` / `appbundle --release`), configure a keystore instead of hardcoding passwords in
+`build.gradle.kts`.
+
+#### 1. Generate a JKS file
+
+```bash
+keytool -genkeypair -v \
+  -keystore android/app/release.jks \
+  -alias release \
+  -keyalg RSA -keysize 2048 -validity 10000
+```
+
+#### 2. Create `android/key.properties`
+
+```properties
+storePassword=YOUR_STORE_PASSWORD
+keyPassword=YOUR_KEY_PASSWORD
+keyAlias=release
+storeFile=../app/release.jks
+```
+
+> `android/.gitignore` already ignores `key.properties` and `*.jks`. Keep these files private.
+
+#### 3. Load the properties in `android/app/build.gradle.kts`
+
+Use Kotlin DSL style configuration:
+
+```kotlin
+import java.util.Properties
+
+val keystoreProperties = Properties()
+val keystorePropertiesFile = rootProject.file("key.properties")
+if (keystorePropertiesFile.exists()) {
+    keystoreProperties.load(keystorePropertiesFile.inputStream())
+}
+
+android {
+    signingConfigs {
+        create("release") {
+            if (keystorePropertiesFile.exists()) {
+                storeFile = file(keystoreProperties["storeFile"] as String)
+                storePassword = keystoreProperties["storePassword"] as String
+                keyAlias = keystoreProperties["keyAlias"] as String
+                keyPassword = keystoreProperties["keyPassword"] as String
+            }
+        }
+    }
+
+    buildTypes {
+        release {
+            signingConfig = signingConfigs.getByName("release")
+        }
+    }
+}
+```
+
+#### 4. Build release artifacts
+
+```bash
+flutter build apk --release
+flutter build appbundle --release
+```
+
+#### 5. CI/CD recommendation
+
+In CI, inject signing values through environment variables or secure secrets storage. Do not commit keystore passwords or
+private keys to the repository.

+## Backend API Integration
+
+The application integrates with two main backend services:
+
+### 1. StackChan Backend (`lib/network/urls.dart`)
+
+- Device registration and management
+- Dance choreography storage
+- User authentication
+- File upload and media management
+
+### 2. XiaoZhi AI Service (`lib/util/XiaoZhi_util.dart`)
+
+- AI conversation and chat functionality
+- Agent management and configuration
+- TTS (Text-to-Speech) voice selection
+- License and activation management
+
+**Base URL Configuration:**
+
+- StackChan Backend: `http://<server-ip>:<port>/stackChan/`
+- XiaoZhi AI: `https://XiaoZhi.me/`
+
+## Development
